SpaceX CEO Elon Musk explains why Blue Origin’s Starship lawsuit makes no sense
For the first time since SpaceX competitor Blue Origin took NASA to federal court after losing a Moon lander contract to Starship and a protest over that loss, unsealed documents have finally revealed the argument Jeff Bezos’ space startup is focusing on in court.
After the details broke in new court documents filed on Wednesday, SpaceX CEO Elon Musk weighed in on Twitter to offer his take on why the arguments Blue Origin has hinged its lawsuit on make very little sense.
While one seemingly significant portion of the main complaint claiming to reveal “additional substantial errors” in SpaceX’s Starship HLS proposal was almost fully redacted, most of the opening argument is legible. In short, Blue Origin appears to have abandoned the vast majority of arguments it threw about prior to suing NASA and the US government and is now almost exclusively hinging its case on the claim that SpaceX violated NASA’s procurement process by failing to account for a specific kind of prelaunch review before every HLS-related Starship launch.
For NASA’s HLS competition, SpaceX proposed to create a custom variant of Starship capable of serving as a single-stage-to-orbit crewed Moon lander with the help of the rest of the Starship fleet – including Super Heavy boosters, cargo/tanker Starships, and a depot or storage ship. SpaceX would begin a Moon landing campaign by launching a (likely heavily modified) depot Starship into a stable Earth orbit. Anywhere from 8 to 14 Starship tanker missions – each carrying around 100-150 tons of propellant – would then gradually fill that depot ship over the course of no more than six or so months. Once filled, an HLS lander would launch to orbit, refill its tanks from the depot ship, and make its way to an eccentric lunar orbit to rendezvous with NASA’s Orion spacecraft and three Artemis astronauts.
As Blue Origin has exhaustively reminded anyone within earshot for the last five months, SpaceX’s Starship Moon lander proposal is extremely complex and NASA is taking an undeniable risk (of delays, not for astronauts) by choosing SpaceX. Nevertheless, NASA’s Kathy Lueders and a source evaluation panel made it abundantly clear in public selection statement that SpaceX’s proposal was by far the most competent, offering far a far superior management approach and technical risk no worse than Blue Origin’s far smaller, drastically less capable lander.
The bulk of Blue Origin’s argument appears to be that its National Team Lander proposal was drastically disadvantaged by the fact that SpaceX may or may not have incorrectly planned for just three ‘flight readiness reviews’ (FRRs) for each 16-launch HLS Starship mission. While heavily redacted, Blue Origin wants a judge to believe that contrary to the US Government Accountability Office’s (GAO) fair assessment that such a small issue is incredibly unlikely to have changed the competition’s outcome, it would have “been able to propose a substantially lower price” for its lander. To be clear, a flight readiness review is an admittedly important part of NASA’s safety culture, but it ultimately amounts to paperwork and doublechecks over the course of a day or two of meetings.
All else equal, the need to complete an FRR before a launch is incredibly unlikely to cause more than a few days of delays in a worst-case scenario and would have next to no cost impact. There is no reasonable way to argue that being allowed to complete some launches without an FRR would have singlehandedly allowed Blue Origin to “[engineer] and [propose] an entirely different architecture.” Nevertheless, that’s exactly what the company attempts to argue – that it would have radically and completely changed the design it spent more than half a billion dollars sketching out if it had only been able to skip a few reviews.
Curiously, Blue Origin nevertheless does make a few coherent and seemingly fact-based arguments in the document. Perhaps most notably, it claims that when NASA ultimately concluded that it didn’t have funds for even a single award (a known fact) and asked SpaceX – its first choice – to make slight contract modifications to make the financial side of things work, NASA consciously chose to waive the need for an FRR before every HLS Starship launch. Only via purported cost savings from those waived reviews, Blue Origin claims, was NASA able to afford SpaceX’s proposal – which, it’s worth noting, was more than twice as cheap as the next cheapest option (Blue Origin).
Ultimately, it thus appears that Blue Origin may have a case to make that NASA awarded SpaceX the HLS Option A contract despite a handful of errors that violated contracting rules and the HLS solicitation. Relative to just about any other possible issue, though, it’s hard not to perceive the problems Blue Origin may or may have correctly pointed out as anything more than marginal and extraordinarily unlikely to have changed the outcome in Blue’s favor had they been rectified before the award. Most importantly, even if Blue Origin’s argument is somehow received favorably and a judge orders NASA to overturn its SpaceX HLS award and reconsider all three proposals, it’s virtually inconceivable that even that best-case outcome would result in Blue Origin receiving a contract of any kind.

Tesla has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
